Mild traumatic brain injury (mTBI), an injury or concussion associated with brief loss of consciousness or altered mental state, has affected as many as 35% of soldiers wounded during recent military actions in Iraq and Afghanistan. Up to 30% of those injured report persistent somatic, emotional and cognitive post-concussive symptoms (PCS) which may adversely impact family life and community re-integration. Marital conflict and intimate partner violence, reported by 54% of OEF/OIF couples, and co-occurring mental health problems may exacerbate cognitive dysfunction and delay rehabilitation. A key contributor to marital conflict is a lack of knowledge about the Veteran's condition and the skills needed to help him compensate for common deficits in memory and planning which create challenges in household management. Despite a growing evidence base for couples treatment for PTSD, there is no established family-based treatment for OEF/OIF Veterans with mTBI, creating a critical research and services gap. The proposed research aims to fill this gap by evaluating a novel form of multi-family group treatment designed to improve community integration (CI) among married/cohabiting OEF/OIF Veterans with mTBI and/or significant posttraumatic stress (PTS) or combat-related stress (CS) by training spouse/partners to aid with rehabilitation and employing disability-adapted communication and problem-solving skills to reduce marital conflict and improve marital satisfaction.
